High in the Pyrenees in the southwest of what is now France, in a time when the Church of Rome proclaims itself the one true religion, heresy has taken hold. The pope sends the Inquisitors of Heretical Depravity to exterminate the heresy. Unbelievers are hunted down, condemned and burned. In 1308, the entire village of Montaillou is taken prisoner. No one is safe -- not even the village priest and the chatelaine of its castle. From the secret files: the extraordinary revelations of village life under the Inquisition.
